Abstract

The invention relates to a medical turn-over bed, a bed head is similar to a rolling bearing and consists of an outer ring 1, an inner ring 8 and a roller wheel 5. The inner ring is connected with a winding drum which is approximately equal to shoulder width, and a bed board is a rolling curtain type bed drawer. In operation, a pin bolt lock (B in figure 1) of a batten at one end of the bed drawer is put into a long hole of a positioning groove (A in figure 1) on the winding drum so as to scroll the patient, and at this time, two groups of belts under the rolling curtain move accordingly. After the bed is rotated to an appropriate angle, the batten with the pin bolt lock is taken down, and the bed drawer is laid flat. The design principle is that the surface contact of the roller wheel and the inner ring is line contact, so the bed has small friction, rotates flexibly and reduces the physical consumption of nurses. The patient can comfortably turn over towards both sides and in a supine gesture, and is always on the central axis of the bed body. The core technology is that by the bed head in a rolling bearing type, the belt which can scroll the bed drawer to bear the bed drawer is scrolled, which is similar to the linear movement of a synchronous belt. Three elements are organically integrated, and combine novelty, creation and practical use.

Description

Medical turn-over bed

This bed is through particular design, can one man operation, and easy to use, simple in structure, frictional resistance is little, rotates sensitively, and the patient can easily finish the side of turning over of different gestures.After now manufacture method of the present invention and operation principle being disclosed in.Medical turn-over bed outward appearance is seen axonometric drawing Figure 11.

(1) manufacture method: see total figure (Fig. 1 of accompanying drawing page 1)

This bed is made up of three parts as can be seen.That is: head of a bed group 1; 2, bedstead group; 3 drawer groups.Grouping now is illustrated in down:

1, head of a bed group: see that (Fig. 2 of accompanying drawing page 1) 4. reaches lower carriage by two side stands on the outer ring 6. to be connected with bedstead.The outer ring with screw connect four pairs of wheel seats 2. install on the wheel seat four rolling 5. the structure of this wheel see (Fig. 5 of accompanying drawing page 2), and the four rolling of seeing from figure two except that because of other physical dimension the bearing of function different choice different model just the same.Two just following rollers are BOGEY WHEELs, and two rollers of both sides, top are locating wheels, play the effect that prevents the inner ring swing.The outer ring part drawing is seen (Fig. 3 of accompanying drawing page 2).The structure of inner ring sees that (Fig. 4 of accompanying drawing page 2) this figure size A is genuine inner ring.For weight reduction easily manufactured, thereby the reel that plays the effect of scrolling roller shutter does not adopt ring flange to connect, but two kinds of functions of a part, the A in the interior loop graph is to view, auspiciously when treating explaination bed drawer group adds explanation.

2, bedstead group: see (Fig. 6 of accompanying drawing page 3)

The bed skeleton is selected 1/2 " steel pipe for use.2. belt in the belt pulley set plays a part bracketing bed drawer.Because of carrying patient's self weight, bed drawer scrolling process is inevitable to produce resistance with belt again.Therefore 3. the belt two ends are equipped with belt pulley, and belt is moving linearly thereupon, and this group belt is similar to synchronous band again for this reason.So select the V-belt for use, because need not seal, be convenient to install to belt, as in order to improve bel-drivenn sensitivity, the axle that the rolling bearing on the belt pulley contacts with it is a tubing, tubing and bearing contact surface promptly can not be processed, also inconvenience installation.What select for use is that the bearing of band sleeve is seen (Fig. 7 of accompanying drawing page 3) for this reason, is two groups at least as for the group number of belt, as selects three groups for use that every group of belt radical can suitably reduce.

3, roller shutter type bed drawer: see (Fig. 8 of accompanying drawing page 4) this drawer by 18 laths 1. two groups of special hinges 2. pin lock 3. Sealing strap 4. form.Size is long, near the outer ledge of two ends inner ring, thereby avoids a drawer front and back displacement in the motion, and size is wide, is slightly larger than the length of run of reel, considers that the patient occupies the wide ≈ 800mm of bed surface all the time.Each π D/4 more than needed of bed both sides when lying on the back.The bed drawer π D/4 that moves right during half-twist left, vice versa.Unnecessary π D/4 long lath because the travel(l)ing rest that the bed drawer has Sealing strap to ride over (Fig. 6) is 9. gone up thereupon, forms interim guardrail, referring to (Figure 10 of accompanying drawing page 4).

The one end plate bar that should use during operation is put into loop graph (Fig. 4) A between two positioning strips of view, presses the inferior pyramidal handle, and rotating handles is 90 ° thereupon, and pin lock can be with end bar and reel card jail under the effect of spring.Promote lath then and make the reel rotation,, designed specific hinge for preventing displacement between the lath.See (Fig. 9 of accompanying drawing page 4).

(2) design principle: (as Figure 12)

The patient edge is greater than shoulder breadth, directly through the circular path scrolling of 500mm, following bracketing belt is done rectilinear motion, ad initio is in plateau to whole patient and turns over side, and health remains on the axis of bed, has creatively broken through the pattern of standing up that traditional " medical turning-over bed " lifts bed board.Selected minimum coefficient of friction for reducing a lot of force parts of resistance.Be similar to the head of a bed group of rolling bearing, be similar to the bracketing belt of synchronous band and bed drawer that can scrolling, simple in structure and novel, the three organically combines.(in a single day this design main parts size is an aluminium alloy, and promotes the use of, produce in batches, aluminium alloy can be made into high-intensity plastic fully) considers the strength of materials certainly, and the geometry of parts is slightly different.

The scope of application: hospital, nursing house, protect old institute and even family (other department or family can remove Lip river alive foot except that hospital uses).

Claims

1. utilize head of a bed both sides colyliform mechanism, drive the rotation of bed drawer.

2. bed board is by the hinge meeting stile, bed drawer that can scrolling.

3. the bed drawer is with belt (V-belt or flat belt, conveyer belt) bracketing, and does rectilinear motion lentamente.

Above-mentioned three core technologies that requirement is this design.
